Method Details

setMaxLength

public void setMaxLength(int maxLength)

Maximum number of characters (in Unicode code points) that the user can enter.

Parameters:

maxLength - the maximum length

getMaxLength

public int getMaxLength()

Maximum number of characters (in Unicode code points) that the user can enter.

Returns:

the maxlength property from the webcomponent

setMinLength

public void setMinLength(int minLength)

Minimum number of characters (in Unicode code points) that the user can enter.

Parameters:

minLength - the minimum length

getMinLength

public int getMinLength()

Minimum number of characters (in Unicode code points) that the user can enter.

Returns:

the minlength property from the webcomponent

setRequired

public void setRequired(boolean required)

Specifies that the user must fill in a value.

NOTE: The required indicator will not be visible, if there is no label property set for the textfield.

Overrides:

setRequired in class TextFieldBase<TextField,String>

Parameters:

required - the boolean value to set

setPattern

public void setPattern(String pattern)

Sets a regular expression for the value to pass on the client-side. The pattern must be a valid JavaScript Regular Expression that matches the entire value, not just some subset.

Parameters:

pattern - the new String pattern

See Also:

• https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#htmlattrdefpattern
• https://html.spec.whatwg.org/multipage/input.html#attr-input-pattern

getPattern

public String getPattern()

A regular expression that the value is checked against. The pattern must match the entire value, not just some subset.

Returns:

the pattern property from the webcomponent

getEmptyValue

public String getEmptyValue()

Specified by:

getEmptyValue in interface com.vaadin.flow.component.HasValue<com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<TextField,String>,String>

Overrides:

getEmptyValue in class com.vaadin.flow.component.AbstractField<TextField,String>

setValue

public void setValue(String value)

Sets the value of this text field. If the new value is not equal to getValue(), fires a value change event. Throws NullPointerException, if the value is null.

Note: Binder will take care of the null conversion when integrates with text field, as long as no new converter is defined.

Specified by:

setValue in interface com.vaadin.flow.component.HasValue<com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<TextField,String>,String>

Overrides:

setValue in class com.vaadin.flow.component.AbstractField<TextField,String>

Parameters:

value - the new value, not null

getValue

public String getValue()

Returns the current value of the text field. By default, the empty text field will return an empty string.

Specified by:

getValue in interface com.vaadin.flow.component.HasValue<com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<TextField,String>,String>

Overrides:

getValue in class com.vaadin.flow.component.AbstractField<TextField,String>

Returns:

the current value.

setRequiredIndicatorVisible

public void setRequiredIndicatorVisible(boolean requiredIndicatorVisible)

Specified by:

setRequiredIndicatorVisible in interface com.vaadin.flow.component.HasValue<com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<TextField,String>,String>

Specified by:

setRequiredIndicatorVisible in interface com.vaadin.flow.component.HasValueAndElement<com.vaadin.flow.component.AbstractField.ComponentValueChangeEvent<TextField,String>,String>

getDefaultValidator

public com.vaadin.flow.data.binder.Validator<String> getDefaultValidator()

Specified by:

getDefaultValidator in interface com.vaadin.flow.data.binder.HasValidator<String>

setManualValidation

public void setManualValidation(boolean enabled)

Specified by:

setManualValidation in interface com.vaadin.flow.component.HasValidation

validate

protected void validate()

Performs server-side validation of the current value and the validation constraints of the field, such as setPattern(String). This is needed because it is possible to circumvent the client-side validation constraints using browser development tools.

onAttach

protected void onAttach(com.vaadin.flow.component.AttachEvent attachEvent)

Overrides:

onAttach in class com.vaadin.flow.component.Component
